contains the total number of deaths worldwide as a result of earthquakes over a 13-year period.

$$\begin{array}{cc}\text{Year}& \text{Total Number of Deaths}\\ \text{1}& \text{231}\\ \text{2}& \text{21,357}\\ \text{3}& \text{11,685}\\ \text{4}& \text{33,819}\\ \text{5}& \text{228,802}\\ \text{6}& \text{88,003}\\ \text{7}& \text{6,605}\\ \text{8}& \text{712}\\ \text{9}& \text{88,011}\\ \text{10}& \text{1,790}\\ \text{11}& \text{320,120}\\ \text{12}& \text{21,953}\\ \text{13}& \text{768}\\ \text{Total}& \text{823,856}\end{array}$$
Use to answer the following questions.
